NEW HAVEN - Gov. Dannel Malloy, Sen. Richard Blumenthal and other officials gathered at Union Station in New Haven Sunday to announce improvements coming to Metro-North's New Haven line.

Starting Monday, workers from the state DOT in conjunction with crews from CL&P will begin work on two new transformers in Cos Cobb. The aim is to implement a "massive backup and redundancy plan" for the line, to avoid power-related interruptions. Four aging transformers will be replaced, Malloy said, almost doubling their power capacity.

The $10 million project comes after a major power outage on the New York side of the line that disrupted service for days last fall. Connecticut's roadways were snarled with traffic as commuters spilled onto the streets to try to make it to their destinations.

The work represents a large investment in the railroad's power structure. Malloy says it's the right time to do the work, after years of "under-investment" in transportation infrastructure.

"I'm committed to getting the Metro-North New Haven line back to where it needs to be to serve the people of the state of Connecticut," Gov. Malloy said. "For too long, we've deferred our problems with temporary fixes, and in some cases, never addressed them at all."

Gov. Malloy said he also requested that the MTA and Metro-North provide him with short- and long-term plans for safety inspections, maintenance, remedial actions and  capital investments. Those plans will be independently reviewed by a separate authority, the governor said.

The governor added that he plans to meet with the MTA chairman and the incoming head of Metro-North within the next week or so to further discuss improvements to the line.
